Term noise is most commonly used to describe disturbing and unwanted ambient sound.
Since I am daily exposed to higher level noise at my workplace, I had a lot of interest to
examine the effects of noise on humans in the working environment. The thesis in
summarized form presents key information relevant to understanding the effects of noise
on human beings and protection against excessive exposure.
Theoretical part of the thesis covers the interpretation of sound as physical quantity, with
an emphasis on the form called “noise”. Showing the differences between perception of
sound in various live beings and consequently a different noise impact depending on their
cognitive abilities. The central part of the theory section consists of Noise in the workplace
and sports environment, where measurement procedures, correction and noise protection
were explained. Thesis also includes chapters legislation and standards, where the most
important documents governing the said area are listed.
In practical part of the thesis, we conducted noise measurements in two different
environments where we spend most of our time. Here we present the noise polluted
environment, the measurement course and the analysis of results from analytical data and
data obtained from questionnaire of exposed individuals. This comparison shows an
important part in sound perception in real life, as it shows the relativity of the fact how
annoying the same level of noise can be for different individuals.
Measures to protect against noise can be implemented in different ways. They are
necessary to maintain healthy hearing and prevent other long-term consequences from
excessive exposure.
